Abstract: A B S T R A C T         A retainer for holding a sheet of insulation against a metal plate comprises a member extending through a hole in the plate and having a flange which sits against the plate.  The member has a longitudinally extending bore terminating at an enlarged chamber.  A rod extends outwardly from the bore and has a head in the chamber.  The rod has a frangible portion suitable for forming a stud by breaking the rod thereat.  Alternately, the rod can simply extend a de-sired length from the bore to form the stud.  In another em-bodiment the stud is unitary with the second end of the member and the weakened portion of the rod is within the bore.          In each embodiment a cap fits over the stud to hold the insulation in place.

Abstract: ABSTRACT    A circuit package exhibiting an excellent heat transfer path from a semiconductor chip or other heat-generating device to the heat-sink can or cover of the package.  A heat-conducting pad is metallurgically bonded to either said cover or a surface of said device; the pad is also separably attached, but metallurgically unbonded, to the other.  In one preferred embodiment, a readily deformable metal or alloy, such as indium, is metallurgically bonded to a limited central region of the heat sink cover.   The deformable metal is separably attached to a major surface of the chip so that there is no stress between the chip or its joints and the solder during the electrical operation of the chip when it generates heat.          The preferred method of fabrication involves the mechanical deformation of a mass of solder against the back side of the chip, after the solder has been metallurgically bonded to heat sink.   The process may be accomplished either at high or low temperatures, depending upon the solder composition and the relative strength of the leads which join the chip to conductive lands on its supportive substrate.

Abstract: PAPER WEB PERFORATING MACHINE                     Abstract of the Disclosure A machine for performing certain operations in the pro-duction of endless business forms has a plurality of cross-perforating knife blades for perforating the endless paper webs at predetermined increments, whereby the perforating knife blades are mounted in slots in the surface of rotating cylindrical bodies and are cutting through the paper webs with their spaced apart perforating knife edges against a rotating "anvil" cylinder which has a hardened, smooth surface.  The cyclic impacts of the perforating blades on the anvil cylinder can become resonant with critical frequencies of the anvil cylinder at certain speeds of the latter and with a certain number of inserted perforating blades causing the destruction of the cutting edges of the former, and therefore the structure of the anvil must be such that no resonances will occur between the cyclic impacts of multiple perforating blades at high speed production operations of the machine.  Similarly the structure of the knife blade cylinder may be such that resonance will not occur and the combined anvil cylinder and knife blade cylinder may be so structured to shift or reduce resonant frequency problems.

Abstract: FREQUENCY SELECTIVE OPTICAL DATA STORAGE SYSTEM            Abstract of the Invention An optical data storage system and method that utilizes the frequency dimension to increase the storage capacity significantly.  The system includes a storage material, for example, in the form of a block, adapted to undergo a photo induced reaction upon exposure to light and which exhibits inhomogeneous absorption line broadening.  Data bits are stored by selective photo induced reactions induced by a narrow band laser at specific frequencies within the broad inhomogeneous line.  The lifetime of these photo induced data bits is of the order of years so as to provide a non-volatile storage system.  In a preferred embodiment, a material is selected so that the photo induced reaction can be made reversible thereby permitting, when desired, the erasing of the data bits.

Abstract: PIVOT JOINT          Abstract of the Disclosure:  An improved wear-indicating pivot joint includes a bearing assembly which supports a stud for both axial and rotational movement.  The bearing assembly prevents sidewise tilting movement of the stud during axial and rotational movement of the stud about its own central axis.  A wear take-up arrangement is provided to compensate for normal wear between a bearing surface and the stud.  The wear take-up arrangement in-cludes a spring which applies a force to a bearing member to continuously urge the bearing surface into engagement with the stud to hold the stud against sidewise tilting movement.  However, upon the occurrence of excessive wear between the bearing surface and the stud, the bearing surface is ineffective to hold the stud against sidewise tilting movement to thereby signal the occurrence of excessive wear.

Abstract: REFUSE COMPACTING VEHICLE     Abstract A refuse carrier is described of the type consisting of a motor vehicle having a compartment adapted to receive and compact refuse.  The novel feature relates to a loading and compacting mechanism comprising a pusher-blade extending across a lower portion of the compartment with a telescopic hydraulic cylinder for moving the pusher-blade horizontally backward and forward between a refuse-receiving position and refuse-compacting position.  A bucket is pivotally mounted along the upper edge of the blade for pivotal movement between a lower refuse-receiving position and an upper refuse-discharging position.  One or more cam wheels is articulated between the bucket and the blade by means of pivotal arms and a cam guideway forms an incline path between a lower refuse-receiving position and an upper refuse-discharging and compacting position.  The cam wheel in response to movement of the pusher-blade in a compacting direction travels up the guideway, thereby forcing the bucket to swing from a lower horizontal refuse-receiving position to an upper vertical refuse-discharging position, with the bucket in the vertical position acting as a vertical extension of the compacting blade during continued movement of the blade in compacting direction.  With the bucket in this vertical position, it can also serve as a pusher for emptying all of the refuse from the container.
